JOHN G. TATE, OF OAKLAND, CALIFORNIA.

PORTABLE HEATER.

To, all whom it may concern:

Beit known that I, J OHN O. TATE, a citizen of'the United States, residing at Oak land, in the county of Alameda and State of 1 California, have invented certain new and useful Improvements in Portable Heaters, of which the following is a specification.

The present invention relates to a stackless heater, adapted for the burning of liquid or gaseous fuel, and by the use of which the air within the room or inclosure in which the heater is positioned will not. become fouled or contaminated, due' to the fumes of the products of combustion rising from the heater.

The invention has for its principal objects to provide a heater having a receptacle or container removably positioned preferably ineach of the heating chambers thereof, within the path of the rising products of combustion, and adapted to contain or hold asuitable chemical compound or material capable of absorbing the impurities and moisture from the products of combustion prior to their escapingfrom the heater to the atmosphere, and to provide a heater wherein the absorbing compound may be readily removed ,therefrom and, renewed when desired, and through which the products of combustion are required to pass prior to escaping from the heater.

With the above mentioned and other ob-- jects in view, the invention consists in the novel construction and combination of parts hereinafter described, illustrated in the accompanying drawings, and pointed; outfin the claims hereto appended, it being understood that various changes in the proportion,

form, size and minor details of construction within the scope of the claims maywberea sorted to without departing from the spirit or sacrificing any of the advantages of i the invention.

7 To more fully comprehendthe invention, reference is directed to the accompanying drawings, wherein- Figure l is a view in side elevation of the preferred embodiment of my heater, disclosing the tops of the heating chambers which permit the positioning of the containers with the compound within the heater.

Fig. 2 is a view in end elevation of the] heater disclosed in Fig. 1, illustrating one of theoutlets for the purified products of combustion.

Fig. 3 is a fragmentary sectional view of Specification of Letters Patent.

Application filed September 21, 1916.

Patented Dec. 30,- 1919. Serial N6.121,4=s1.

Fig. 1 showing two heating chambers, one beingfilled with-a purifying material and intact, while the other has thematerial and covering cap removed therefrom.

Fig. 4 is a modified form of support for the purifying material.

Fig. 5 is a view in plan of the modified form of support.

Referring more particularly to the several views of the drawings, wherein like characters of reference designate corresponding parts,1 indicate the sections of a suitable heater of the radiator type, and said sections connect preferably at their base through al-ined openings-2,. through which the fuel pipe'3, provided with the burner openings, passes.

Each section is provided with a combustion chamber 5, at the base thereof, which communicates with the heating chamber 6 at the upper portion ofthe section. The air required for combustion is preferably admit ted through an opening 7 below the combustion chamber. A removable head 8 is positioned over and closes the upper portion of the heating chamber, and the same is provided with outlet openings9 in opposite sides of the wall thereof. Suitable baffle walls 10 extend inwardly and upwardly from the bottom and side. edges of the openings 9-and project a distance above the upper-ledge: thereof, thereby providing a re tarding wall or baflie for the products of combustion rising in the heating chamber, before: thesame atmosphere. To insure the rigid seating of the head 8 onto-theperipheral Wall 11 of the heating chamber casing, an annular in wardly extended offset 12', having the downwardly projecting portion 12, is provided at-the lower edge of the head, and when the head" is in position, as in Fig. 2,.the outer face of the portion 12. extendssa slight distance below the upper ,edge of tlie wall 11 in contact with the inner surface thereof,

1 and with the lower edge resting on a suitable are released or pass to the:

' tion of pressure within the heating cham- 1 in the chambers. The basket-s or containers are supported within the heating chambers in any suitable manner, preferably by the inwardly projecting lugs 16 on which the base of the baskets or containers rest. The baskets or containers are adapted to contain a suitable compound or material having properties of absorbing moisture'and the impurities, such as carbonic acid gas, from the products of combustion rising in the heater, and this material or compound is preferably. in the form of small spheres or balls 17, although it may be in any other suitable for 1 which will permit the products of combustion rising in the heating chamber to pass through the body in the container, prior to escaping from the outlet openings into the room or inclosure.

In the form shown by Figs. 4 and 5, the basket or container is modified and comprises suitable plate 18, perforated as at i9, the same resting on and supported by the lugs 16. A handle 20 extends upwardly from the center of the plate to facilitate theremoval thereof from the heater. lVith this form of support the absorbing material or compound is not capable of removal from thevheater in a body, but the same provides a more cheaply constructed support than that disclosed in the other views.

It will be apparent that the products of combustion in their escape to the atmosphere are caused to pass through the body of purifying material which absorbs the impuritles and moisture therefrom; also that the walls 10 extended upwardly above the openings 9 retard the passage of the products to the atmosphere and cause the formaber which retards the rising of the gases of combustion, glvmg the same a longer per od to contact with the purifying compound. It

is also apparent that access may be easily had to the purifying material by simply removing the heads 8 wnich permit either the removing of t'le containers or support for the material. or the examining thereof.

YVhile I have illustrated the preferred embodiment of my invention in the form of a heater of'the radiator type and employ ing gas as fuel,it is to be understood that any form of heater, using any form of fuel,

may be employed, just so long as the prodnets, of combustion before escaping therefrom are caused to pass through the body of purifying material and means are provided forobtaining access to the interior of theheater for the renewal of the purifying material. Having thus described my invention what inwardly from their inner faces below their open end, andan open receptacle removably disposed in the upper ends of each section and supported by said lugs, said receptacle having openings in its walls and being adapted to contain a purifyingmaterial, each of said caps havingheat outlets in their side walls, and baflle plates within said caps forming trap pockets enveloping and extending above said outlets and open only at their upper sides, said receptacles being removable through the upper ends or" the sections when the caps are removed.

A heater of the kind described comprising a vertical tubular section having an open upper end, a chambered cap-section detachably and freely resting upon the open upper end of said tubular section, a source of heat supply in the base of said tubuler section, an open receptacle supported in the upper end of said tubular section and through the upper end of the tubular sec- 171011 when the cap is removed.

In testimony whereof'l have signed my name to this specification inthe presence of two subscribing witnesses;
